I recommend using the official app to replenish the balance via Sber, TON or BTC. Personally, I always check the fees and instructions to ensure the transfer is safe. The app makes the process convenient and transparent: you can choose the best method, and the transactions are fast. My recommendation for beginners is to carefully study the replenishment steps and check the details to avoid mistakes. Personally, I have used the app and found it to be safe and convenient. This way you can manage your funds without risk and focus on the game.
